Returns are usually treated as a cost to minimize. The more useful view is that a return is a customer telling you something, and the moment they start one is the last chance to keep the sale.
We set up Loop so the return journey is self-serve and steers toward an exchange or store credit before a refund, with incentives that make that genuinely attractive rather than obstructive. We also connect return reasons back into merchandising, because a size that gets returned constantly is a product page problem, not a returns problem.
